TELEGRAPH AND TELEPHONE CONDUCTOR.

SPECIFICATION forming part of Letters Patent No. 289,890, dated December 11, 1883.

Application filed August 28, "=3.

T aZZ whom, it may concern:

Be it known that I, J OSEPHUS O. CHAMBERS, of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Aerial Telegraph and Telephone Conductors, of which thefollowin g, in connection with the accompanying drawings, is a specification.

It is well known that when two or more conductors of electricity are placed in electrical proximity to each other, as in telegraph and telephone lines, every signal or sound transmitted over one by the variations of the electrical current will produce in the others in- I 5 duced currents in the opposite direction, and which disturb and interfere with the use of the others forseparate or distinct signals or sounds.

The object of my invention is to greatly reduce, if not wholly prevent, this disturbing action of induction in aerial telegraph and telephone electric conductors; and my invention consists in the combination, with one or more aerial conductors insulated from the supports and connected with the batteries and ground- 2 5 ed in the usual manner, of one or more induction wires, rods, bands, or strips arranged upon the supports in electrical proximity to the telegraph and telephone electric conduct ors, and insulated from the supports from the telegraph or telephone electric conductors and from the earth, and so as not to form acomplete or closed circuit, substantially as hereinafter more particularly described and claimed.

The mode of carrying my invention into cf- 3 5 feet will be understood by reference to the accompanying drawings, in which- Figure l is a perspective representation of an aerial telegraph or telephone line embodying my invention, and Figs. 2 and 3 represent side elevations of the same, showing different forms of induction-wires.

A represents the usual posts orsupports for the telegraph or telephone electric conductors or wires B, which are insulated from said supports by means of glass insulators 0, usually employed for that purpose.

D represents the usual battery, and (Z the electric conductors or wires leading from the battery to the ground. Upon the top of each (X0 model.)

pole or support A is attached aglass insulator, E, preferably such as shown and described in Letters Patent of the United States of America, No. 19%,220, granted and issued to me on the 14th day of August, 1877.

F represents an induction wire, rod, band, or strip, which is arranged upon or secured to the insulators E above and in electrical proximity to the telegraph or telephone electric conductors or wires B, and upturned, and having one or more points, a, at its terminal ends, as shown, and is, by means of the insulators E, insulated from the posts or supports, from the telegraph or telephone electric conductors or wires, and from the ground, and so as not to form acomplete or closed circuit. In long-distance or multiple aerial telegraph or telephone lines I securely attach to or upon the induction wire, rod, band, or strip F, at suitable intervals, metallic barbs I), having two or more points, as shown in Fig. 2, or make the strip or band F in spiral form, as shown in Fig. 3, so that the edges thereof shall present points in opposite directions, and for the purpose of more completely diffusing the induced electricity contained upon the induction-wire F, and which is opposite to that contained upon the electric conductors or wires B upon said conductors or wires 13, thereby greatly reducin g, if not wholly preventing, the disturbing or retarding action of the inductive influence of said electric conductors or wires upon each other, and of the atmospheric electrical disturbances upon said conductors or wires. In the event that there are a large number of telephone or telegraph electric conductors or wires 13 arrangedupon the same supports, I arrange one or more induction wires, F, not only above such electric conductors or wires, as shown in the drawings, but between two or more or below such wires, as shown at F, and in electrical proximity thereto, for the purpose aforesaid.

It is wellknown that if a charged conductor of electricity be brought near an uncharged conductor which is insulated and not connected with the earth the charged conductor acts upon the uncharged conductor by induction and separates its polarities, and that the or DETROIT,

charged conductor attracts the dissimilar electricity nearest to it and repels the similar electricity to the farthest points of the uncharged conductor. It is also well known that an electrical conductor, when insulated from the earth, receives its electricity by induction, and is opposite from that of the body from which it was induced, and that a conductor receiving electricity by conduction orfrom contact receives the same kind as contained upon the body in contact therewith; hence'it will appear in the example shown that the telegraph or telephone electrical conductors B, which are connected with the earth, receive, to illustrate, negative electricity therefrom, or the same kind with which the earth may be charged, and, if brought in electrical proximity to the induction wire, rod, or band F, will induce upon the base of F positive electricity, when both the positive and negative will approach each other and become equalized, and the inductive action of the conductors or wires B will be on the induction-wire F, and thereby greatly reduce, if not wholly prevent, the disturbing 0r retarding action of induction upon the wires B.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination, with a telegraph or telephone line consisting of one or more electrical conductors insulated from the supports and connected with the earth, of one or more induction wires, rods, bands, or strips arranged in electrical proximity to the telegraph or telephone electrical conductors, and insulated from the supports, from the telegraph or telephone electrical conductors, and from the earth, and having its terminal ends disconnected, so as not to form a complete or closed circuit, substantially as and for the purpose specified.

2. The combination, with an aerial telegraph or telephone line consisting of one or more electrical conductors insulated from the supports and connected with the earth, of one or more induction wires, rods, bands, or strips arranged in electrical proximity to the telegraph or telephone electrical conductors, and insulated from the supports, from the telegraph or telephone electrical conductors, and from the earth, and having its terminal ends turned upward and pointed, substantially as shown and described, and for the purpose specified.

3. The combination, with an aerial telegraph'or telephone line consisting of one or more electrical conductors insulated from the supports and connected with the earth, of one or moreinduction wires, rods, bands, or strips arranged in electrical proximity to the telegraph or telephone electrical conductors, and insulated from the supports, from the telegraph or telephone electrical conductors, and from the earth, and having its terminal ends turned upward and pointed, and provided at intervals between its terminal ends with electrical conducting barbs or points pointing in opposite directions, substantially as shown and described, and for the purpose specified.
